The force acting on a body of mass 10 kg is 100 N. The distance covered by the body in 10 seconds, if it starts from rest, is:
Correct answer: B. 500 m
- A. 100 m
- B. 500 m
- C. 1000 m
- D. 5000 m
Explanation
Explanation:First, find the acceleration: a = F/m = 100 N / 10 kg = 10 m/s².Then, use the kinematic equation: d = ut + (1/2)at². Since the body starts from rest, u = 0.d = 0 + (1/2)(10 m/s²)(10 s)² = (1/2)(10)(100) = 500 m.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
